Microsoft tenant information
Frustrated with the time it took find Microsoft tenant information? Tired of
navigating the Microsoft 365 Admin Portal and directing users to specific pages just
to find basic details like Tenant ID, primary and default domain names?
We created this tool to help you find Microsoft tenant information effortlessly.
Microsoft is enhancing security in Exchange Online by updating federation information. Previously, this allowed unauthenticated users to retrieve all federated domain names for a tenant. The update, rolling out mid-June, will only return the domain specified in the query, preventing unauthorized exposure of tenant domain information.
This change has impact on retrieving primary domain (*.onmicrosoft.com) of a tenant. For more details, please refer to the
original announcement.
